本地通知不在設備上工作，但在模擬器上工作

Question

我已經閱讀了一些如何使用UILocalNotification的指南。 所以自從我第一次嘗試以來，我已經嘗試過並且沒有成功。 要在AppDelegate.m中注冊通知，我使用：

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    {
    ...
    //if it is iOS 8
    if ([application respondsToSelector:@selector(registerUserNotificationSettings:)])
    {
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge|UIUserNotificationTypeAlert|UIUserNotificationTypeSound) categories:nil];
        [application registerUserNotificationSettings:settings];
    }
    else // if iOS 7
    {
        UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
        [application registerForRemoteNotificationTypes:myTypes];
    }

    UILocalNotification *locationNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
    if (locationNotification) {
        // Set icon badge number to zero
        application.applicationIconBadgeNumber = 0;
        }

        return YES;
    }

並在應用程序運行時收到通知：

    - (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
    {
    NSLog(@"notification recieved %@",notification.alertBody);
     //  NSLog(@"notification userinfo %@",notification.userInfo);
    UIApplicationState state = [application applicationState];
    if (state == UIApplicationStateActive) {
        NSLog(@"notification fired in foreground");
         UIAlertView *message = [[UIAlertView alloc] initWithTitle:@"Notification!"
                                                      message:notification.alertBody
                                                     delegate:nil
                                            cancelButtonTitle:@"OK"
                                            otherButtonTitles:nil];

    [message show];
    } else if (state == UIApplicationStateInactive){
        NSLog(@"notification fired in inactive");

    } else if (state == UIApplicationStateBackground){
        NSLog(@"notification fired in background");
         }


    }

一切都在模擬器和設備上都可以 - 當應用程序運行時，我得到了我的重復通知。 但我需要在應用程序未運行時收到通知， 即應用程序處於非活動狀態時（主頁按下一次）

問題是，如果我按下按鈕按下我的通知，例如，我會毫無問題地得到它，它將顯示在通知中心，徽章將添加到我想要的應用程序圖標上。 但我希望只在我的AFNetworking任務結束時收到通知。

要設置通知，我使用以下方法：

    -(void)getProgress{
    [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES];
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    NSString *token = [defaults objectForKey:@"token"];
    NSString *header = [NSString stringWithFormat:@"Bearer %@",token];
    NSDictionary *params = @{@"lang": @"en",@"project":projId};
    manager.responseSerializer = [AFJSONResponseSerializer serializer];
    [manager.requestSerializer setValue:header forHTTPHeaderField:@"Authorization"];
    [manager POST:@"http://example.com/api/get-progress" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
        if ([[responseObject objectForKey:@"result"]isEqualToString:@"success"]){
            progCreate = [responseObject objectForKey:@"progress"];
            if ([progCreate intValue]==100){
                //shedule notification for immediately showing
              UILocalNotification* localNotification = [[UILocalNotification alloc] init];
              localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:0];
              localNotification.alertBody = [NSString stringWithFormat:@"Notification text!"];
              localNotification.alertAction = @"Show";
              localNotification.timeZone = [NSTimeZone defaultTimeZone];
              localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
              [localNotification setSoundName:UILocalNotificationDefaultSoundName];
              [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
             //  [[UIApplication sharedApplication]presentLocalNotificationNow:localNotification]; the same result as above
            }

        }

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];
        NSLog(@"Error: %@", error);
        }];
    }

主要問題是此方法僅適用於iOS版本8.0的模擬器，並且不適用於iOS 7.1.1的iPhone 4和iOS 8.1的iPhone 5c，它也不適用於iOS 7.1的模擬器。 在iOS 7.1+的真實設備和模擬器上，我從來沒有注意到在后台接收通知，只有在我打開應用程序時才會得到它（然后它會顯示我在AppDelegate.m設置的警報）我很高興任何建議和任何幫助。

我看到你正在使用Objective-C。 考慮到一年前問過這個問題，你可能要么想出這個問題，要么你現在正在使用Swift 2.0。 我有同樣的問題，我可以通過添加以下代碼解決它與Swift 2.0。

AppDelegate.swift ：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.

    application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil))
    application.beginBackgroundTaskWithName("showNotification", expirationHandler: nil)

    return true
}

你可以在這里看到我的完整答案。

您在iOS 8.0+模擬器中收到通知的事實是iOS模擬器運行時的限制。 在設備上，當您的應用在后台時，它實際上並未運行，任務將被暫停。 在iOS模擬器中，任務繼續在后台運行。

有時我們不會立即收到本地通知，但在1小時后我幾乎得到通知。 所以，等待一段特定的時間然后再檢查一下。
